Abstract in different language:	Paper provides the summary of the FEM simulation of elasto-plastic strains and stresses in the course of the local indentation of a steel pipe by a spherical indenter. The FEM calculation was performed according to the recommendation of API 579-1 / ASME FFS-1 2007 for Level 3 dent assessment. Series of 65 FE calculations of the elasto-plastic state of the indented tubes was performed. The combination of three tube diameters D = 508, 920 and 1420 mm with the ratios between the diameter and the wall thickness D/h = 91, 76, 64, 51 and 37 resp. were used. The diameters of the spherical rigid indenters were 100 and 200 mm, the depth of the indent varied gradually from 75 to 150 mm. The residual stresses and strains in the vicinity of the dent after the relieving of load were determined together with the depth and length of the resulting dent.
